Man-made carbon dioxide affects ocean acoustics
Oceanographers Tatiana Ilyina and Richard Zeebe of the University of Hawaii, together with Peter Brewer of the Monterey Bay Aquarium Research Institute write in the journal Nature Geoscience that seawater sound absorption will drop by up to 70 percent already during this century.

Global warming likely to be amplified by slow changes to Earth systems
Researchers studying a period of high carbon dioxide levels and warm climate several million years ago have concluded that slow changes such as melting ice sheets amplified the initial warming caused by greenhouse gases.

Metastasis formation revealed in detail and real time
If metastases develop in the brain a patient's prognosis is poor.

Scientists take a step towards uncovering the histone code
DNA's packaging can be just as important and intricate as the information in the DNA itself.

Gefitinib improves survival compared with standard chemotherapy in lung cancer patients with genetic mutation
Patients with the most common form of lung cancer (non-small-cell lung cancer) who have mutations in the epidermal growth factor receptor (EGFR) gene have significantly improved progression-free survival if they are treated with gefitinib compared with standard chemotherapy.

Boston University reseachers develop faster, cheaper DNA sequencing method
Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification.

Next generation lens promises more control
Duke University engineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail.

Global temperatures could rise more than expected, new study shows
The kinds of increases in atmospheric carbon dioxide taking place today could have a significantly larger effect on global temperatures than previously thought, according to a new study led by Yale University geologists.
